Introducing the PCIe-DIO24
Chapter 1
Overview: PCIe-DIO24 features
This manual explains how to install and use the PCIe-DIO24 board. The PCIe-DIO24 is a digital I/O board
designed for the PCI Express (PCIe) bus.
The PCIe-DIO24 provides 24 lines of digital I/O with selectable 3.3 V and 5 V logic levels. The 24 DIO lines
are organized into three groups of 8-bits each (Port A, Port B, and Port C). Port C can be further divided into
two four-bit ports (Port C-HI and Port C-LO). The direction of each port is independently configurable with
software for either input or output. Digital outputs are HC logic and can source and sink 2.5 mA.
The PCIe-DIO24 has a 10 k resistor network associated with each digital port. You can configure each port for
pull-up or pull-down with software. On power up and reset the configuration of each port is read from
EEPROM. The board is shipped with each port configured in the pull-up state.
The PCIe-DIO24 emulates the 82C55 Programmable Peripheral Interface (PPI) chip. Measurement
Computing's Universal Library and Windows driver supports mode 0 only.
Digital I/O lines are accessible through a 37-pin D-type connector. The board has two individual slow blow
fuses rated at 0.375 amp to protect the +VDIO and +12V outputs on the connector. One spare fuse is provided.
Software programs written with the Universal Library for the USB-DIO24/37, PCI-DIO24 and CIO-DIO24
devices are fully compatible with the PCIe-DIO24.
Power is provided by the PCI Express slot. The PCIe-DIO24 board is completely plug-and-play. All board
addresses are set by the board's plug-and-play software. Board configuration is controlled by your system's
BIOS.

PCIe-DIO24 User's Guide
Installing the PCIe-DIO24
Installing the hardware
The PCIe-DIO24 is completely plug-and-play. Configuration is controlled by your system's BIOS. To install
your board, follow the steps below.
Install the MCC DAQ software before you install your board
The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install the
MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on installing
the software.
1.
Power off and unplug the computer, and remove the cover to expose the expansion slots.
2.
Touch any metal part of the computer to discharge static electricity that may be present. Static electricity
can damage the board.
3.
Insert the PCIe-DIO24 into an unused x1 PCIe expansion slot.
The PCIe-DIO24 is designed to install into an x1 slot. However, you can also install the board into an
unused x4, x8, or x16 PCIe slot.
Caution! Ensure that you install the board into a PCIe slot. Installing the PCIe-DIO24 into a non-PCIe slot
can damage both the board and the computer’s motherboard.
4.
Close your computer and turn it on.
A dialog box opens as the system loads, indicating that new hardware has been detected. The information
file for this board should have already been loaded onto your PC when you installed the Measurement
Computing Data Acquisition Software CD supplied with your board, and should be detected automatically
by Windows. If you have not installed this software, cancel the dialog and install it now.
5.
Run InstaCal to test your installation and to configure the pull direction of the digital port resistors.
Refer to the Quick Start Guide that came with your board for information on how to initially set up
InstaCal.

Functional Details
82C55 emulation
The PCIe-DIO24 emulates the 82C55 Programmable Peripheral Interface (PPI) chip. Measurement
Computing's Universal Library and Windows driver supports mode 0 only.
Whenever the board is powered on or reset, all pins are set to high-impedance input. Based on standard TTL
functionality, these inputs typically float high, and may have enough drive current to turn on external devices.
Consequently, if you have output devices such as solid state relays, they may be switched on whenever the
computer is powered on or reset. To prevent unwanted switching, and to drive all outputs to a known state after
power on or reset, configure each port resistor with InstaCal.
Unconnected inputs float to the pull direction
Unconnected inputs will float in the pull direction that is configured for the port with InstaCal (either up/high or
down/low).
Replacing a fuse
The PCIe-DIO24 has two individual 0.375 amp slow blow fuses. One fuse is connected to the 12V output at pin
16, and is labeled F7 on the board. The second fuse is connected to both +VDIO outputs at pin 18 and pin 20, and
is labeled F6 on the board. A spare fuse is installed on the board at location F4. All fuses are secured to the
board with clips for convenient replacement.
A fuse will blow during operation if amperage exceeds 0.375 amp. If you need to replace a fuse, perform the
following procedure.
1.
Hold the center of the blown fuse and pry it from the fuse holder clip.
2.
Insert the replacement fuse into the fuse holder clip.
